You need to make sure you supply all intermediate certificates. You can also combine them in a .pem file like this:

your private key
your certificate
(intermediate) CA certificate lowest in the hierarchy
other CA certificates higher in the hierarchy...
(intermediate) CA certificate highest in the hierarchy

Make sure there are no extra lines and carriage returns.
